Y Murakami, M Schüler - Physical Review B, 2022 - APS
High-harmonic generation (HHG) in solids is a fundamental nonlinear phenomenon, which
can be efficiently controlled by modifying system parameters such as do** level and …

Shear-strain controlled high-harmonic generation in graphene

T Tamaya, H Akiyama, T Kato - Physical Review B, 2023 - APS
We propose a method for controlling the high-harmonic generation (HHG) with a high
dynamic range in single-layer graphene. We find that, by utilizing shear strain, a significant …

Efficient control of high harmonic terahertz generation in carbon nanotubes using the Aharonov-Bohm effect

Y Murakami, K Nagai, A Koga - Physical Review B, 2023 - APS
We show that high harmonic generation (HHG) in carbon nanotubes (CNTs) can be
efficiently controlled using the Aharonov-Bohm (AB) effect. When a static magnetic field (B) …

High-harmonic generation in GaAs beyond the perturbative regime
